Overwintering Houseplants

Q. I would like to bring some of my patio plants indoors for the winter. Is it necessary to change the soil or repot them first?

A. Most plants do not appreciate being repotted in early fall. This chore is best done in spring right before a plant begins its new growth. If your patio plants are insect- and disease-free and have thrived in whatever pot and mix they are in, let them stay this way throughout winter. You can repot them in spring, using a fresh soilless mix. Decide whether their pot size should be increased at that time too. Check the undersides of pots and saucers for any insects, and consider spraying your plants with an insecticidal soap before bringing them indoors.
